Filed: 1971-05-24
Abstract: 1351817 Colour television MAGNAVOX CO 24 May 1971 [25 May 1970] 16687/71 Heading H4F A colour television receiver for NTSC signals includes a flesh-colour corrector circuit 37 which causes all vectors in the range of 67 to 191 degrees relative to the B-Y axis to be shifted towards a preselected flesh vector at 123 degrees. With switch 38 closed the output on line A from circuit 37 causes the output of burst circuit 29 to lag its input by 15 degrees, to cause demodulation about axes at - 15 degrees and + 75 degrees relative to the B-Y axis. The output on line B from circuit 37 to phase shifter 31 causes the demodulation axis at + 75 degrees to be advanced 18 degrees to +93 degrees, and the output on line C from circuit 37 to B-Y demodulator 28 causes a reduction in the amplitude of the colour signal component along the demodulation axis at - 15 degrees. Amplifier 32 effectively causes the pseudo-(R-Y) demodulation axis to be advanced by 8 to +101 degrees and the psuedo-(B-Y) demodulation axis to be retarded by 8 to - 23 degrees. The receiver may be adapted for use with PAL signals by including a matrix circuit. The demodulation axis changes can alternatively be carried out in amplifier 32.

Title: Improvements in or relating to visual course indicators for radio directive systems
IPC: G01S1/02
Filed: 1941-12-26
Abstract: 581,126. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. Dec. 26, 1941, No. 16695. [Class 40 (v)] In visual course indicating apparatus of the kind operated by overlapping radio beams modulated with complementary dot-and-dash signals, and in which a dynamometer type indicating instrument has applied to one winding the variable component of the rectified received signal and to the other the original signals or a wave derived therefrom, the variable component of the rectified received signal is applied both to one winding of the dynamometer instrument and to a full-wave rectifier, the variable component in the rectified output from which is applied to the other winding. The derived wave is effective to operate the indicator during substantially the whole of the dot-and-dash signal period instead of only a fraction of the period, as in the arrangement described in Specification 526,114. In the apparatus shown, the wave-forms at audio, signal, or intermediate frequency from a receiver tuned to the transmission are rectified by a diode D1 and, after removal of the D.C. component by a condenser C1 large enough to pass the keying frequency, are amplified by a triode portion of the valve and passed by way of a condenser C2 to a full-wave bridge rectifier and one coil of a dynamometer course-indicator M in series. The rectifier produces the same wave-form across the resistance R4 for both the dash-and-dot transmissions, and this is applied to the other coil of the dynamometer M through a condenser C3 which removes the D.C. component. The deflection is therefore positive or negative according as a dot or dash signal is being received. A second diode D2 may be provided for AVC. A sharp filter may be used which selects the fundamental dot frequency to diminish interference and noise.

Filed: 1944-09-05
Abstract: 580,023. Electromagnetic relays. BRITISH INSULATED CABLES, Ltd., QUAYLE, J. C., and JONES, P. Sept. 5, 1944, No. 16915. [Class 38 (v)] [Also in Group XXXV] In an arrangement wherein the operation of a relay B occurs a certain time after the closure of a switch S, the relay B is operated by the discharge of a condenser C' which is charged at a predetermined rate after the closing of switch S and is switched over at d from the charging to the discharging condition by a delay switch D. If therefore switch D acts prematurely, the condenser C' will not be sufficiently charged to operate the relay B. In the arrangement shown, the closing of switch S connects the A.C. supply M to lines F leading to a heating circuit for a hot-cathode mercury vapour rectifier and, after the time interval, the operation of contacts b by the relay B connects the supply M to the anode circuit H. The delay switch D is a thermal switch and is in parallel with a circuit containing a rectifier K, a resistance R<1> and the condenser C'. After operation of the relay B it is maintained by a secondary circuit derived from a transformer T. In a modification, the thermal switch D is replaced by a rectifier in series with a neon lamp and relay which are in parallel with a condenser. The condenser slowly charges up till a discharge occurs through the neon lamp and the relay is operated to switch over the other condenser C' to its discharging position.

Abstract: 707,417. Weighing apparatus. WHEELERWEIGH Ltd. July 14, 1952 [July 18, 1951], No. 16999/51. Class 143 [Also in Group XXX] A mobile lifting truck has the load engaging and lifting member, e.g. a fork, mounted on a load mast structure normally directly supported on the chassis and a weighing mechanism movable from an inoperative to an operative position between the chassis and load mast structure in which it raises the latter off its supports on the chassis so that the structure and load are carried entirely by the weigh mechanism. As shown, the fork and all the fork-lifting and guiding means are carried on tilting masts 8x pivoted at 14 on load masts 8 at each side of the chassis supported when in weighing position on knife-edges 12 of a main weighbeam 7 fulcrummed on fixed knifeedge seatings 5 and consisting of pairs of levers embracing the load masts 8 and connecting transversely by a rod 9. The masts 8 are also supported at the top from the chassis by links 17 forming with the weighbeam arms parallelogram supports. From the cross-rod 9 a twin arm 19 rearwardly extends and is connected by a rod 21 through knife-edge centres with a transverse lever system, Fig. 3, connected to a dial indicator. One lever 23 is fulcrummed in a housing 24 movable into either of two positions by a hydraulic cylinder and piston and control valve 26 so that in non-weighing position the housing is raised and the weighbeam rocked so that its knife-edges 12, Fig. 1, are lowered until finally disengaged from the masts 8 by fitments on the latter being stopped by and received in fixed conical seatings 36 of the chassis. The rocking movement is also further continued so that abutments 38, not shown, on the weighbeam 7 engage fixed stops which then act as fulcra about which the weighbeam further pivots until its fulcrum knife-edges 5 are also raised clear of their seatings. The conical seatings 36 may be above and/ or below the weigh beam. To keep the truck steady during weighing operations hydraulic jacks may be actuated, simultaneously with the weighing position hydraulic cylinder, to lower to the ground, by means of bell-crank levers, spring- loaded stabilizing jacks 39. Dial indicator. This is operated by a rod 35 from the lever 31, through a lever, ribbon, cam and segmental gear against the action of pendulum or other resistant. The pointer makes four revolutions for the full angular movement of the pendulum and an index pointer moves with the latter to indicate the additional weight to be added to the main pointer reading. The reading scale is mounted on a boss passing through the glass window of the indicator to permit adjustment to zero to compensate for sloping ground altering the pendulum position for taring off the weight of any fitments on the truck forks, and may be arranged to be read from the side of the truck or from the driver's seat, and may be illuminated by a lamp automatically switched on by the weighing position mechanism.
